我想在点击提交时更改$ this-＆gt; fields_form中字段的值，即在值进入表格之前我想更改我要插入的表单值
// This form is populated when add or edit is clicked
public function renderForm()

这里我想更改winner_image_name（字段）的值，即当图像上传时我想更改字段名称，如果图像没有上传，我想保留默认值
public function getContent()
{
$output = null;
if( Tools::isSubmit('submitAddkits_winners') )
{
// d("rechaed here");
$winner_image = $_FILES['winner_image'];
$ticket_no = (string) Tools::getValue('ticket_no');
//d($ticket_no);
if( $winner_image['name'] != "" )
{
//Format allowed i
$allowed = array('image/gif', 'image/jpeg', 'image/jpg', 'image/png');
//check allowed formats
if( in_array($winner_image['type'], $allowed) )
{
$path = '../modules/addwinners/';
$ext = pathinfo($winner_image['name'], PATHINFO_EXTENSION);
$newfilename = round(microtime(true)) . '_'.$ticket_no;
$this->fields_value['winner_image_name']=$newfilename.".".$ext;
$helper->fields_value['winner_image_name'] = "";
if( ! move_uploaded_file($winner_image['tmp_name'], $path.$newfilename.".".$ext) )
{
$output .= $this->displayError( $path.$stilogo_image['name'] );
return $output.$this->displayForm();
}
}
else
{
$output .= $this->displayError( $this->l('Image formated Not Supported.') );
return $output.$this->displayForm();
}
}
//Se arrivo qui è perchè tutti i campi obbligatori sono stati riempiti quindi aggiorno i valori
//Configuration::updateValue('STILOGOPOPUP_IMAGE', $winner_image['name']);
// $output .= $this->displayConfirmation( $this->l('Impostazioni salvate') );
}
return $output.$this->html;;
}

我认为你应该使用postProcess或者使用另一种方式使用Init（），但下面的例子是postProcess
public function postProcess()
{
parent::postProcess();
$id = (int)Tools::getValue('id_blahblah');
$file = Tools::fileAttachment('img_any');
if (!empty($file['name']) && $id > 0)
{
if (ImageManager::validateUpload($file, Tools::convertBytes(ini_get('upload_max_filesize'))))
die('Image size exceeds limit in your PrestaShop settings');
if (!is_dir(_PS_IMG_DIR_.'blah'))
@mkdir(_PS_IMG_DIR_.'blah', 0777, true);
if (!is_dir(_PS_IMG_DIR_.'blah/'.$id))
@mkdir(_PS_IMG_DIR_.'blah/'.$id, 0777, true);
$path = _PS_IMG_DIR_.'blah/'.$id.'/';
$absolute_path = $path.$file['name'];
move_uploaded_file($file['tmp_name'], $absolute_path);
$imgPath = 'blah/'.$id.'/'.$file['name'];
//Save in DB if needed
Db::getInstance()->execute('UPDATE `'._DB_PREFIX_.'blah`
SET `img` = "'.pSQL($imgPath).'"
WHERE `id` = '.(int)$id);
}
}
